Algae re-entering pool while vaccuming

Ok so I got my Intex 2650 sand filter in and running and decided to vaccum some today. Well when I hit the algae on the bottom at the middle of the pool it seemed to just recirculate into the pool. Is there a way to stop this from happening?>

Re: Algae re-entering pool while vaccuming

Im in the process of cleaning up a swamp from over the winter and was shocking wit bleach. Everything was a nice blue color til I tried vacuuming it up. It sucked through the vac but came back through the return.

Well when I tried to skim some off the top with my skimmer net i noticed that the algae would just pretty much disentegrate and pass theough the net. I figure thats what is happening when it passes through the sand filter

Yes I have the next day the pressure was up and the water was at a trickle at th return so I backwashed then rinsed then restarted but I noticed the pressure hasn't climbed a whole lot since then. I think I'm gonna take the 6 way off and look at the sand see if I can see any channeling

Also I didn't really mention it but it returns in a reen cloud not as whole algae particles. I removed the 6 way and did whatg they suggest to the sand when you suspect channeling so I'm gonna let it run a bit and try it out again and see what I get.

Well???? What's the verdict? Enquiring minds want to know.

Well I pulled the valve shoved a hose in and out the sand til the water cam out clear. then leveled the sand backwashed, rinse and restarted. I let it filter for a while then re-vacuumed. There wasn't as much coming through but still got a green fog coming back into the pool. How would I go about checking the 6 way for problems?

Re: Algae re-entering pool while vaccuming

When vacuuming very fine debris, it is not uncommon for a cloud of micro-particles to get through the sand. Sand can only filter down to a certain level, and the rest will pass right through. If the flow rate is excessive for the filter, then the amount of unfiltered material will be even greater and more noticeable. Mustard algae is especially difficult to filter with a sand filter.
